Abstract

This invention relates to an improved high efficiency solar cell with a 'HEGC stack-dichroic mirror-MEGC stack' architecture or a 'HEGC stack-dichroic mirror-MEGC stack-LEGC stack' architecture. The improvement comprises the addition of a silicon cell to act as a scavenger cell to absorb light that would otherwise not be absorbed and to convert that energy to electricity. The silicon cell is positioned adjacent to the cell with the smallest energy gap of the cells in the MEGC stack.
